Re: Parallel safety tagging of extension functions

The case I imagined was if someone would use these functions on the 
result from a slow CTE and would want the CTE to be executed in 
parallel. I have no idea if that is a realistic case, but I rarely use 
adminpack in my own work.

Agreed.

Yeah, but since it is just one function I think it makes sense to change 
it when we already are bumping the version of the extension. I think it 
makes sense to skip whole extensions, like chkpass or bloom, but if it 
is just a few functions where it does not matter, why not tag them as 
safe? Personally I think the churn which really matters is if we have to 
bump the extension version or not.
